Button Hinge Structure for Low-Wobble, Low-Reactive-Force Pressing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional button hinge structures either lead to button wobbling due to single-point support or increased reactive force and poor pressing feel due to dual-side support, particularly when hinges are arranged at four corners.
Innovation Solution
A hinge structure for buttons featuring a combination of first and second flexible hinges, where the first hinge is coupled to one end of the button main body and the second hinge is coupled to the first hinge, providing stability and reducing reactive force by allowing the button to move without applying large pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If one end portion of the button is supported by a hinge, then the button can be pressed easily, but the button becomes likely to rotate and wobble
Solution Approach 1:
The hinge structure is divided into two separate hinges instead of one, with the first hinge supporting one end and the second hinge supporting the other end. This segmentation provides stable support while maintaining ease of pressing operation.
2Stability of the object's composition
If both end sides of the button are supported by hinges, then the button stabilizes, but reactive force increases and pressing feel worsens
Solution Approach 1:
The two hinges are positioned at different locations along the button - the first hinge at one end and the second hinge at a position closer to the center. This asymmetric local arrangement provides stability while distributing reactive force to improve pressing feel.
3Stability of the object's composition
If hinges are arranged at four corners of the button, then the button stabilizes, but reactive force greatly increases
Solution Approach 1:
Instead of using four hinges at the corners, the invention extracts and uses only two strategically positioned hinges. This reduction in hinge数量 lowers the reactive force while maintaining sufficient stability for button operation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively suppresses button wobbling and reduces reactive force, improving the pressing feel and enabling compact button arrangement while maintaining stability and reducing manufacturing costs.
Implementation Method 1
a first hinge (4D) having flexibility, and being coupled to the button main body (4B) at one end and coupled to the contact portion (4G) at another end, and a second hinge (4E) having flexibility

AI summary
For suppressing wobbling of a button while suppressing reactive force generated when the button is pressed, a hinge structure of a button includes a contact portion contacting a substrate on which the button is arranged, a button main body varying in a relative positional relationship with the substrate, a first hinge having flexibility, and being coupled to the button main body at one end and coupled to the contact portion at another end, and a second hinge having flexibility, and being coupled at one end to a position in the button main body on an opposite side on which the first hinge is coupled to the button main body, and coupled at another end to the first hinge at a position in the button main body on a side on which the first hinge is coupled.
